ABSTRACT:
The nozzle beam on a device for producing liquid streams for stream interlacing of fibers, for example of a fiber web guided along the beam, consists of an upper part that extends over the working width of the fiber web and a lower part fastened thereto in a fluid-tight manner. On the nozzle beam, on its lower part, a nozzle sheet is mounted with the holes for the nozzles in a fluid-tight manner by means of a sealing O-ring. This O-ring can be replaced without disassembling the lower part from the upper part. In order for this to be readily possible, in the nozzle beam, over its entire length and width and opposite the bearing groove for the O-ring of the lower part, in the upper part of the nozzle beam, a repair groove is provided which is dimensioned vertically slightly larger than the thickness of the O-ring. By means of the repair groove, an elongate strip on which a replacement O-ring is mounted can easily be inserted. The elongate strip carries the O-ring in a considerably stretched state so that its diameter is reduced. The bearing groove is made open at the ends of the nozzle beam so that the O-ring in the stretched state can be introduced, by means of a positioning strip that is inserted into the repair groove, into the bearing groove that is made swallowtail-shaped. Because of the narrowed outer cross section of the bearing groove, the O-ring which is then relaxed can no longer fall or float out of the bearing groove.
